Minimum Iguana Enclosure Dimensions

Don't make the mistake of starting with an iguana enclosure that's too small - iguanas grow quickly. The following table shows you the minimum enclosure dimensions needed based on the average size in snout-vent length (SVL) and snout-tail length (STL) for the first seven years. So, unless your iguana is full grown, when its STL is more than two-thirds the enclosure width, it's time for a new enclosure.
